During an assessment of the cranial nerves, the nurse finds the following: Asymmetry when the client frowns, uneven lifting of the eyebrows, sagging of the lower eyelids, and an escape of air from the right side when the client puffs their cheeks. This would indicate the dysfunction of which of the cranial nerves?
Motor component of IV (Trochlear)
Motor and sensory components of XI (Accessory)
Motor component of VII (Facial)
Motor component of X (Vagus) and sensory component of XII (Hypoglossal)
The Correct Answer is C
A) Motor component of IV (Trochlear): The trochlear nerve primarily controls the superior oblique muscle of the eye, which is responsible for downward and lateral eye movements. The findings described do not relate to eye movement and therefore do not indicate dysfunction of this nerve.
B) Motor and sensory components of XI (Accessory): The accessory nerve innervates the sternocleidomastoid and trapezius muscles, primarily affecting head rotation and shoulder elevation. The symptoms noted in the assessment do not pertain to these muscle functions, so this option is not correct.
C) Motor component of VII (Facial): The signs of asymmetry in frowning, uneven eyebrow lifting, sagging eyelids, and air escaping when puffing the cheeks are characteristic of dysfunction in the facial nerve (cranial nerve VII). This nerve controls the muscles of facial expression, and impairment would lead to the described asymmetrical movements.
D) Motor component of X (Vagus) and sensory component of XII (Hypoglossal): The vagus nerve affects autonomic functions and some swallowing muscles, while the hypoglossal nerve controls tongue movements. Neither nerve is primarily responsible for the facial expressions described in the assessment findings, making this option incorrect.

Correct Answer is B
Explanation
A) Have the client smile, frown, and puff out their cheeks: This test assesses the facial nerve (cranial nerve VII), not the trigeminal nerve (cranial nerve V). While important for evaluating facial movement, it does not specifically test the motor function of the trigeminal nerve, which is responsible for mastication.
B) Palpate the masseter muscles when the client clenches their teeth: This is the correct test for assessing the motor function of the trigeminal nerve. The trigeminal nerve innervates the muscles responsible for chewing, and palpating the masseter muscles during clenching allows the nurse to evaluate muscle strength and function. It provides insight into the motor capabilities associated with this cranial nerve.
C) Assess constriction of the client's pupils with direct and indirect light: This test evaluates the function of the optic nerve (cranial nerve II) and the oculomotor nerve (cranial nerve III). It does not assess the trigeminal nerve and is not relevant for this assessment.
D) Ask the patient to turn their head left and right with resistance: This action tests the spinal accessory nerve (cranial nerve XI), which is involved in neck movement. It does not relate to the function of the trigeminal nerve, making it an inappropriate choice for this specific assessment.
Correct Answer is ["A","C","D"]
Explanation
A) Texture: Assessing the texture of the skin is an important part of a comprehensive skin assessment. It provides insights into the health and hydration status of the skin. Normal skin texture should feel smooth and even, while changes can indicate issues such as dryness or conditions like eczema or psoriasis.
B) Tachypnea: This term refers to an increased respiratory rate and is not a characteristic assessed in the skin. While it can indicate a physiological response to various conditions, it does not relate to skin health or characteristics and therefore is not relevant in this context.
C) Turgor: Skin turgor refers to the elasticity and hydration status of the skin, which can be assessed by pinching the skin. Proper turgor indicates adequate hydration, while decreased turgor can signal dehydration or other health issues. This is an essential component of skin assessment.
D) Temperature: Assessing the temperature of the skin can provide information about circulation and potential inflammation or infection. Normal skin temperature should feel warm and consistent, while variations can suggest underlying conditions such as fever or shock.
E) Tympany: Tympany is a term used in percussion assessments of the abdomen and is not applicable to skin assessment. It refers to a hollow sound produced by tapping on a body surface and does not pertain to skin characteristics.
